Geologically-Consistent Rock Physics Modeling for Sandstones – Modulus-Based Prediction of In Situ Elastic Properties

F045 GEOLOGICALLY-CONSISTENT ROCK PHYSICS MODELING FOR SANDSTONES: MODULUS- BASED PREDICTION OF IN SITU ELASTIC PROPERTIES Summary 1 In this paper we describe a new model capable of robust predictions of elastic properties (Vp and Vs) for consolidated sandstones. The model is based on a new set of high quality laboratory velocity measurements each supported by detailed petrologic evaluation and rigorous evaluation of rock and fluid acoustic properties from well data. We develop relationships between porosity and dry rock moduli (bulk and shear) using laboratory velocity data for a geologically diverse set of quartzdominated lithified sediments. The model performs well in
